If you want to dramatically improve handling performance while reducing wheel hop in your Cobra IRS, the Maximum Motorsports IRS Delrin Control Arm Bushing Kits is just what the doctor ordered! Your OE rubber control arm bushings allow deflection that can destroy your handling; these bushings improve your handling and reduce your wheel hop by completely eliminating that deflection. The Delrin bushings precisely locate the rear control arms to help maintain the rear wheel alignment in a manner that is impossible with the stock rubber bushings. While they provide adequate suspension control, and noise and vibration reduction, rubber bushings cannot accurately position the control arms well enough to achieve maximum performance from the suspension. Get the most out of your Mustang with performance suspension parts from MM and Stangmods!
